SocketIO session and Express session is not synced

[AlexInCube]

When I change something in a session using express, this data does not appear in the socket io. Even using session.save

Express:

app.get('/getUserGuilds', async (req, res) => {
    if (req.session.user) {
      oauth.getUserGuilds(req.session.user.access_token).then((userGuildsList) => {
        const botGuildsList = []
        userGuildsList.forEach((element) => {
          const guild = client.guilds.cache.get(element.id)// Бот проверяет только те гильдии, в которых он присутствует.

          if (guild?.members.cache.find(user => user.id === client.user.id)) {
            botGuildsList.push(element)
          }
        })
        req.session.guilds = botGuildsList
        req.session.save(() => {
          res.send({ botGuildsList })
        })
      })
    } else {
      res.status(401).send({})
    }
  })

I get socket.request.session without guilds field

SocketIO:

socket.on('joinAudioPlayer', guildId => {
      socket.request.session.reload(function () {})
      socket.rooms.forEach((room) => {
        socket.leave(room)
      })
      const guilds = socket.request.session.guilds
      // console.log(socket.request.session)
      if (guilds) {
        if (guilds.some(guild => guild.id === guildId)) {
          socket.join(guildId)
        }
      }
    })

Hi! I think you need to move the room logic in the socket.request.session.reload() callback:

socket.on('joinAudioPlayer', guildId => {
  socket.request.session.reload(function () {
    socket.rooms.forEach((room) => {
      socket.leave(room)
    })
    const guilds = socket.request.session.guilds
    // console.log(socket.request.session)
    if (guilds) {
      if (guilds.some(guild => guild.id === guildId)) {
        socket.join(guildId)
      }
    }
  })
})

Please see the example here: https://socket.io/how-to/use-with-express-session

I'm incredibly stupid, for some reason I completely ignored the callback in reload. Thanks you.
